Cash Flow (FCF) Calculation Formula

Free Cash Flow (FCF) Calculation Formula

Free Cash Flow (FCF) is a crucial financial metric that represents the cash generated by a business after accounting for investments in non-current capital assets, such as property and equipment. It’s calculated using the formula:

Free Cash Flow (FCF) = Cash from Operations – Capital Expenditures (CapEx)

It demonstrates the cash that a company can produce after covering essential expenses like asset purchases. Investors are particularly interested in FCF because it indicates how much discretionary cash a company has available, which can be used for dividends, debt repayment, or reinvestment in the business.

Different Types of Free Cash Flow

While FCF is a widely recognized term, it can refer to various metrics. The most common forms include:

  1. Free Cash Flow to the Firm (FCFF), often called unlevered free cash flow.
  2. Free Cash Flow to Equity (FCFE), also known as leveraged free cash flow.
  3. Generic Free Cash Flow (FCF), is the focus of this discussion.

Each type has a specific use depending on whether the company’s equity or the entire firm is being analyzed.

Deriving Free Cash Flow from Financial Statements

If the cash flow statement isn’t available, FCF can still be calculated using information from the income statement and balance sheet. Here’s a step-by-step guide to deriving FCF:

Step 1: Operating Cash Flow and Net Income

Cash from operations (CFO) is calculated by taking net income and adding back non-cash expenses while adjusting for changes in non-cash working capital items such as accounts receivable (AR), inventory, and accounts payable (AP). The formula for CFO is:

CFO = Net Income + Non-Cash Expenses – Changes in Non-Cash Working Capital

Step 2: Non-Cash Expenses 

Non-cash expenses are those that appear on the income statement but do not directly impact cash flow. Common examples include depreciation, amortization, stock-based compensation, and gains or losses on investments. The formula for non-cash adjustments is:

Non-Cash Adjustments = Depreciation + Amortization + Stock-Based Compensation +      Impairment Charges +/- Gains/Losses on Investments

Step 3: Changes in Non-Cash Working Capital 

Calculating changes in non-cash working capital involves tracking the difference in key balance sheet items, such as accounts receivable, inventory, and accounts payable, from one period to the next. The formula is:

Changes = (Year 2 AR – Year 1 AR) + (Year 2 Inventory – Year 1 Inventory) – (Year 2 AP – Year 1 AP)

Step 4: Capital Expenditures (CapEx) 

Capital expenditures can also be calculated using the balance sheet. The formula is:

CapEx = Year 2 PP&E – Year 1 PP&E + Depreciation

Step 5: Combining the Components 

Bringing all the components together, the full FCF formula is:

FCF = Net Income + Non-Cash Expenses – Increase in Non-Cash Working Capital – Capital Expenditures

For simplicity, the FCF formula is often broken down into more manageable calculations as outlined in the first four steps, rather than combining them all at once.

Importance of Free Cash Flow

FCF helps management make informed decisions about future investments and expansions that can increase shareholder value. Positive FCF indicates that a company can cover its expenses, reinvest in growth opportunities, or reduce debt. In contrast, negative FCF suggests the company may need to raise funds through external sources.

From an investor’s perspective, FCF is a crucial metric for evaluating the financial strength of a business. Companies with healthy FCFs are generally seen as good investment opportunities, especially if their share prices are undervalued. This is because FCF is directly linked to stock valuation and a company’s ability to service debt.

Levered vs. Unlevered Free Cash Flow

When discussing FCF, finance professionals may also refer to two specific forms: levered and unlevered FCF.

  • Levered Free Cash Flow (FCFE), or Free Cash Flow to Equity, accounts for a company’s interest payments and is used to evaluate the cash available to equity holders.
  • Unlevered Free Cash Flow (FCFF), or Free Cash Flow to the Firm, excludes interest payments and is used to value the entire firm.

The key distinction is that levered FCF considers a company’s debt obligations, while unlevered FCF provides a broader view of its financial health without factoring in interest expenses.

FCF in Financial Modeling and Valuation

Understanding FCF is essential for financial modeling in corporate finance, particularly investment banking and equity research. For example, discounted Cash Flow (DCF) models are founded on the belief that investors are entitled to a company’s free cash flows. These models value companies by analyzing the timing and amount of projected FCF.

Limitations of Free Cash Flow

While FCF is an invaluable tool for assessing a company’s financial health, it has limitations. Accrual accounting, which net income relies on, can sometimes be manipulated. While it’s harder to manipulate cash flows, some companies may delay paying debts or accelerate cash collection to improve their FCF numbers.
